sensible suggestion from Wysiwig there I thought.

Scooby - why shouldn't stewards enforce the rules for dog owners same as all other rules, whatever the festival decides they are? at most festivals it would be a stewards job to ask somebody to stop making noise in the middle of the night, for example. If somebody is such a nuisance that they are asked to leave the festival, it often does become an issue for festival directors to step in but warnings etc usually come from the stewards at first.
